12 Inch Class 600 Slab Gate Valve, ASTM A216 WCB, API 6D

Summary

12 Inch Class 600 Slab Gate Valve, ASTM A216 WCB, API 6D is designed for isolation in oil and gas, power generation and industrial process piping. gate construction is aimed at on/off isolation with low pressure drop when fully open; flanged ends support bolted pipeline integration and inspection access. Carbon-steel pressure parts suit general hydrocarbon and utility service when corrosion allowance and coating are defined on the data sheet. Typical duties include oil & gas, chemical processing, general industrial service. Confirm end connection, trim, actuation and inspection scope against the approved project data sheet.

Advantages

Selection advantages

  • Select NPS and pressure class inside the published catalogue envelope; freeze the working size on the data sheet before GA release.
  • Design basis and face-to-face follow the standards shown in the technical grid; do not assume a single standard covers every option.

Plant application
